Nov. 1, 1932. c. c. BOGARDUS UPPER CYLINDER OILEH Filed March 14, 1929 Patented Nov. 1, 1932 PATENT CHARLES c. BOGARDUS, or LOS ANGELES, cannon-ma UPPER CYLINDER :OILER Application filed March 14, 1929.

My invention relates to an upper cylinder oiler of the particular type disclosed in U. S. Letters Patent No. 1,634,134, issued to me June 28, 1927, and the principal object of my present invention is to generally improve upon and simplify the construction of the oiler disclosed in my aforesaid patent, as well as other oilers that are designed for providing lubrication for the upper portions of the cylinders of internal combustion engines and the valve stems and other moving parts that are associated with the upper portions of the engine cylinders.

Further objects of my invention are to combine with an upper cylinder oiler, a sight feed arrangement that is preferably located on the steering post of the vehicle or at some other point within the vehicle that is readily visible to the driver, further to provide a convenient support and holder for the containers of the liquid lubricant, which containers are produced in standard forms and sizes, and further to provide an upper cylinder oiler that is relatively simple in construction and which may be advantageously employed for lubricating the upper portions of the cylinders of all internal combustion engines.

I Further objects of my invention are, to

provide simple means for regulating the flow of liquid lubricant through the sight feed attachment that is combined with the oiler, and further to provide the over illumination for the sight feed attachment, so that the operation thereof may be observed at night.

With the foregoing and other objects in view my invention consists Fig. 1 is a diagrammatic View of my improved oiler and showing the sight feed por- 7 tion thereof in position on the steering'column 40 of a motor vehicle. 1

bodiment of my invention, 10 designates a container which may be of standard form and size and principally constructed of metal. This container is provided at its upper end, with a tubular neck 11, the latter being externally threaded for the reception of a cap 152 that serves as a closure for said container.

Seated in and extending through the cap 12 is a small vent tube 13, and seated in said cap and extending downwardly therefrom is a suction tube 14, the lower end of which terminates adjacent to the bottom of the containerwhen the cap 12 is properly positioned thereupon.

This container, which serves as a reservoir for the liquid lubricant that is used in oiling the upper portion of the engine cylinders is located at a convenient point on the vehicle adjacent to the engine, preferably at a point adjacent tothe carburetor 15 and for receiving and holding the container in position I utilize a bracket of the. type illus trated in Fig. 2.

This bracket, which is formed from a single piece of sheet metal comprises back plate 16 that is secured to a fixed part of the vehicle by screws or bolts and projecting forwardly from the lower end of this plate is a horizontally disposed shelf 17, upon which 86 the bot-tom of the container 10 is adapted to rest.

Projecting forwardly from the upper end of plate 16 and atthe sides thereof is a pair of horizontally disposed fingers 18 that engage on top of the body of the container 10 that is positioned in the supporting bracket.

Formed integral at and projecting forwardly from the side edges of plate 16 are curved arms 19 that are adapted to engage the intermediate portions of the sides of the container that is positioned in the bracket. The middle from which the bracket is formed has a certain degree of resiliency and as result the fingers 18 and arms 19 yieldingly engage the container that is positioned in the bracket and firmly hold same in proper position without vibration while the car is in operation.

Located at a convenient point within the 19p vehicle in front of the driver and preferably on the upper portion of the steering column is a small housing 20, having a transparent front wall 21, through which the interior of the housing is readily visible and located in the top of said housing is a valve housing 22, having a depending nozzle 23. Arranged for operation within the valve housing is a needle valve 24, which may be readily adjusted, so as to control the flow of lubricant through the valve housing and leading from the upper end of the suction tube 14 through the rear wall of the housing 20, and thence to the valve housing 22 above the discharge opening therefrom is a small suction tube 25.

Leading from the lower end of housing 20 to the feeding 26 that is arranged on the vacuum tank 15 and to which the gas line 27 is connected, is a suction tube 28.

Those portions of the tubes 25 and 28 that parallel each other may be enclosed in a suitable protecting tube of armor, preferably a flexible metal cable 29.

Formed in one of the side walls of housing 20 is an opening 30 that is closed by a transparent section 31 of glass or the like, and arranged on the exterior of the housing 20 immediately over this transparent section is a small housing 32 that encloses a small electric lamp 33 and Which latter is supplied with current from a suitable source of supply, preferably the batterv that forms a part of the starting and lighting system of the car.

Thus the interior of the housing 20 may be illuminated at night so that the operation of the sight feed attachment of the oiler may be readily observed.

When the engine with which my improved oiler is associated, is in operation the suction produced in the vacuum tank 15 or the pump that is effective in delivering oil to the carbureter produces suction through tube 28, and the suction prevails within the housing 20.

Upon opening the middle valve 24 suction is brought through tube 25, that is connected to tube 14, which latter extends to the bottom of the lubricating container 10, and as the result of the suction the liquid lubricant is drawn from the container through tubes 14 and 25, and this lubricant discharges through V the open valve in the top of the housing 20 and passes from the lower portion of the chamber within said housing through the tube 28 to the vacuum tank or pump and from the latter to the carburetor. Within the latter the lubricant is mixed with the gaseous vapor that is drawn into the combustion chambers of the engine so as to efl'ectively lubricate the upper portions of the cylinders and the valves and other operating parts that are associated with the upper portions of the cylinders.

By adjusting the middle valves 24 the flow of liquid lubricant to the carbureter may be very accurately regulated and controlled and the flow of lubricant through the housing 20 may be readily observed through the transparent front Wall 21.

Tube 13 functions as a vent to permit air to enter the container 10, thus enabling the device to function properly until all of the liquid lubricant has been withdrawn from the container and at the same time counteracting any tendency of lubricant to flow from the container as a result of siphonic action.

While I have shown suction pipe 28 connected to the Vacuum tank it will be understood that said tube may be connected to a pump or like device that is operated from the cam shaft of the engine and which effects a positive feed of oil to the carbureter.

Thus it will be seen that I have provided an upper cylinder oiler that is relatively simple in construction, inexpensive of manufacture and installation and very effective in performing the functions for which it is intended.

The use of a supporting bracket enables standard forms and sizes of containers to be changeably used in the system and the sight feed attachment enables the operator of the vehicle to readily observe at all times the flow of liquid lubricant through the oiler and by adjusting the middle valve the flow of liquid lubricant may be very accurately regulated and controlled.

It will be understood that minor changes in the size, form and construction of the various parts of my improved upper cylinder oiler may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim as my invention:

1. The combination with an internal combustion engine and its fuel suction means, of a liquid lubricant container, a housing pro- "ided with windows, a source of light arranged on the exterior of the housing adjacent to one of said windows, a valve in the upper portion of said housing, a suction tube leading from the liquid lubricant container to said housing and a suction tube leading from said housing to the fuel suction means associated with the engine.

2. In an upper cylinder oiler, the combination with a liquid lubricant container, the suction tube leading therefrom, of a sight feed located in said suction tube and comprising a housing having a window and a valve located in the upper portion of said housing for regulating the flow of liquid lubricant through said housing, and means for illuminating the interior of said housing.

In testimony whereof, I aliix my signature.
